Bro, my dad came here illegally. Eventually was granted amnesty and brought my mom, me, and three of my siblings over into a one bedroom apartment. I remember sleeping on sleeping bags in that first apartment. He was the only source of income. Worked his ass off as a construction laborer. I don't remember him ever missing work. He provided all the essentials but nothing past that. We lived within our means and eventually moved into a bigger apartment, then into a house. He had his priorities and finances in order.
Your position in life is, more often than not, a reflection of what you put into it. I don't buy most of these sob stories.
Your brothers aren't really who I'm talking about. They're homeowners in a really expensive market, so that and the fact that their career isn't something you can find just anywhere probably means they're professionals who can live there if they want. I'm talking about low income renters in retail, fast food, blue collar work, etc that stay in really expensive places even though it makes no financial sense to do so.
